The utility model relates to shield tunnel survey receiving equipment. The shield tunnel survey receiving equipment comprises a detector, a clearing device and a positioning device, wherein the clearing device is used for being inserted into a grouting hole; and the positioning device is used for feeding the detector into the grouting hole. The positioning device comprises a positioning rod, an outer sleeve, an inner sleeve and a first spring, and the positioning rod is in threaded connection with the inner sleeve; the outer sleeve coaxially sleeves the periphery of the inner sleeve; the at least three first springs are arranged around the positioning rod in the circumferential direction at intervals; one end of the first spring is connected to the positioning rod, and the other end of the first spring is connected to the outer sleeve. Therefore, the detector can be tightly attached to the rock wall through the positioning rod, so that the accuracy of a detection result is improved. Meanwhile, the first sprin
